There is a consensus in the literature that provider – generally hospital – concentration causes higher commercial medical prices. Newer literature has examined the supply side of the market to examine whether concentrated insurers successfully lower premiums. But there is almost no research connecting these two literatures, investigating the combined dynamics of provider and insurer concentration on costs and premiums. This project investigates whether the association of provider market concentration and hospital costs and insurance premiums differs by insurance market competitiveness.
